Please follow general Kuryr instructions for creating a Docker network that
uses Kuryr as its backend, and for launching containers on that network. Then
if you look at the IP routing table and iptables, you will see Calico routes to
the containers.

Calico for containers without Kuryr

The Calico project also provides networking for containers more directly,
without Neutron and Kuryr as intermediaries. Please see Getting
Started for details.
